Methanization is one of the key technologies of the circular economy and green growth. Within the framework of the Energy Transition Act, France has set itself the target of ensuring that 10% of the gas it consumes will originate from renewable sources by 2030. The development of methanization is one of the main levers to achieve this objective. The sector is expanding rapidly with 80 additional installations and the doubling of the production of biomethane injected into the natural gas networks in 2017. To achieve the objective by 2030, the Renewable Energy Liberation Plan provides for various incentive mechanisms. These include simplification measures at the regulatory level.
